@max-sixty That's exactly it. What's really weird for this is that the original code in Satpy is using a dask array and not a numpy array. It seemed very strange to both copy the DataArray (.copy()), convert the dask array to a numpy array (np.asarray), and then still get a read-only array.

I can understand how xarray would treat numpy arrays and dask arrays the same when it comes to this, but coming from outside the project it is very surprising that a dask array would be marked as read-only when it was used to just create a "new" numpy array.

Feel free to close this or use it as a marker to clarify some documentation or error messages as mentioned in #2891.
